Woolworths Credit Card. It's 4 days since I transferred money into my card. It is still not reflecting.

First off: I do enjoy shopping at woolies and find the stores are well stocked with great foods, are clean and the staff are incredibly helpful. However Woolworths, you really have to do something about whomever runs your credit cards as they are totally ***********. I do know that for some reason deposits made into the card usually take 2 days to reflect, which is inexplicable as all other eft's I do, will reflect that same day or at the latest within 24 hours. I knew that I would be buying more than usual over the festive period, so I transferred additional monies into my card four days ago, it does still not reflect. This type of incompetence is totally unacceptable.
